2020 Audi Q7

In July 2023, my 2020 Audi Q7 experienced a complete electrical failure at highway speeds due to a Belt Starter Generator (BSG) malfunction. Audi replaced the BSG with the same faulty part. Months later, I noticed increased oil consumption and loud engine noise. Despite multiple service visits and reporting these issues, Audi failed to properly diagnose the problem. In January 2025, despite a clear check engine light indicating a problem, Audi dismissed my concerns. Just weeks later, in February 2025, the engine catastrophically failed due to undiagnosed internal damage. Audi repeatedly ignored diagnostic warnings and failed to address my complaints, putting my safety at risk. Audi consistently dismissed my concerns, attributing engine noise and oil consumption to normal wear. The failures posed safety risks, including sudden loss of power while driving. Despite documented defects, Audi refused to take responsibility or perform proper diagnostics, resulting in continued safety hazards. I am formally requesting NHTSA to investigate the widespread issues affecting the 2020 Audi Q7, including the BSG system and excessive oil consumption leading to engine failure.” Additional Details: •Component/System Failure: The 48V Belt Starter Generator (BSG) and the engine failed. The vehicle is available for inspection upon request. •Safety Risks: The electrical failure at highway speeds caused a sudden loss of power. The engine failure posed a risk of the vehicle shutting down unexpectedly while driving. •Problem Confirmation: The Audi dealership confirmed the engine failure and acknowledged the presence of metal shavings in the oil, indicating severe internal damage. •Inspections: The vehicle has been inspected by the Audi dealership, and Audi representatives acknowledged the issue. •Warning Signs: The check engine light illuminated in January 2025. Additional symptoms included loud engine noise (‘tractor-like’) and increased oil consumption, which Audi dismissed.

Panoramic sunroof imploded while traveling at freeway speeds (70mph) during normal conditions (no rain, hail, snow, etc. and 60* temp) causing a large amount of glass to be blown into the cab of vehicle, striking the driver and passenger. With this loud implosion and visibility obstructed by flying glass debris it put the driver in a unsafe environment. This also put the passenger and other drivers on the road at a huge risk of an accident. Throughout the automotive industry, this has been a known issue over the past several years and even at the local Audi dealership in Bellingham, WA. After conversation with dealership there was no known contributing factors to the implosion and was suspected to be a manufacturing defect.

The Audi 2020 q7 experiences an SOS Emergency contact communication failure when it goes of cell service range and in certain circumstances, it does not reset itself Or allow reconnection to the communication module after it goes back in range within cell service. This is a know issue, similar to Audi service Bulletin 90T2 in which the NHTSA issued a recall (The Q7 model is not covered under That recall, but several other models within the same year are covered). As a result of this software bug, in certain circumstances, it the communication module may not be able to contact emergency services. Audi America dealerships require payment and charge consumers $276 for drivers to update the MMI system To correct the software “bug.” Due to the fact that it is a Software issue, which requires updating by the dealership, Extended warranties do not cover fees associated.

while driving the vehicle, I received a warning that there was an electrical system failure. Then the entire care shut off in the middle of the highway. There was no way to get the vehicle into neutral to push it to a safer location out of traffic. I was in the vehicle with my two children. This left us stranded in the middle of the highway with a significant amount of traffic. There was no way to get the vehicle back on. This seems to be a known issue with Audi and they have notified the dealerships about it but have not issued a recall. Please expedite this as a recall. There could not have been a more dangerous situation for me and my children.

The contact owns a 2020 Audi Q7. The contact stated that while driving approximately 55 MPH, the messages "Electrical Malfunction" and "Stop Vehicle" were displayed. The contact stated that moments later the vehicle shut off and failed to restart. The vehicle was towed to the residence and later examined by an independent mechanic who diagnosed that the alternator was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were contacted regarding the failure, but no assistance was provided. The failure mileage was 70,000.

Our 2020 Audi Q7 (50,100 miles) suffered a catastrophic electrical failure while traveling on the freeway at 65+MPH. Suddenly the engine warning light went on, and then seconds later the entire interior lit up like a Christmas tree before it succumbed to a complete and catastrophic electrical failure. EVERYTHING failed – the car had zero power. No acceleration, brakes, steering, SOS, hazards / turn signals, brake lights, airbags, door locks, etc. My wife and child sat there in a steel box traveling at a high rate of speed while obstacles navigated around them; had they been hit, the air bags would not have deployed. This car nearly cost me my family. Audi replaced the alternator and the battery, and denied my buy-back claim because the incident hasn’t happened multiple times, and therefore doesn’t qualify for the lemon law. We continue to experience problems with the car – most recently: acceleration hesitation and recent warning lights saying 1. camera sensor failure (only to have them start working again), 2. tire pressure warnings (despite all the tire pressures being normal), and 3. warnings notifying me that lights are out (despite all lights operating normally). I believe Audi is underestimating the severity of the situation. We were fortunate that the initial failure on the freeway did not result in injuries or fatalities. I cannot fathom the idea of waiting for the vehicle to fail multiple times before taking it off the road, potentially putting lives at risk. The car has only been serviced at Audi dealerships. My family and I no longer feel safe in this car. While selling it is an option, I cannot, in good conscience, endanger someone else's life by not disclosing the vehicle's history and the well-known electrical defects Audi has.
